Application filed lltareh 523, 192i. Serial No. 154,691.

To all to 7mm it mayconcern no it known that 1', FRANK L. Bowman, a citizen oil the United States, residing at liilorgnuitown, in the county of hflonongalia s v y and state oi li est Virginia, have invented a new and useiliul. ll enholiler, of which the following a specification.

This invention is a.- pen holder having means tor releasing pen points from engagement therewith.

Une of the objects of the invention. is to provide a simple and inexpensive device, by means of which the pen point may be readily disengaged from the pen holder, no matter how badly it may have become corroded by the ink. A further object is to provide a device of the character mentioned which will prevent accidental disengagement of the pen and pen holder while in use. A fur ther object is to provide a pen holder, having a releasing device in which there are no protruding parts to interfere with its nor real use.

The invention will be hereinafter fully set lforth and particularly pointed out in the claims.

in the accomltianying drawing:-

liigure 1 is a side elevation illustrating a pen holder with the invention applied thereto. Figure 3 is a sectional view on the line 3-3, Figure 1, illustrating the positions of parts when the pen. holder is in use. Fig ure t is a similar view illustrating the positions of the parts when the pen point is to be released. Figure 2 is a detail view illustrating the pen holder with the releasing sleeve removed.

Referring to the drawing, 10 designates the body of the pen holder, which may be of any preferred length or shape, the same be ing provided at one end with a spindle 12, which is offset with respect to the axis of the body 10. liotatably mounted upon the spin" die 12 is a releasing sleeve 13, having a slot 14-. extending inwardly from one end, said slot being of the approximate width of the shank otl a standard pen point, conventionally illustrated at 1.5. lit will be noted that the spindle 12 provided with awrecess 16, oi? approximate size and shape to accommodate the shank of the pen point.

lln practice the sleeve 13 and the spindle 152, are so proportioned that the recess 16 may be brought approtrinnely to center of the pen holder, s illustrated in l me 3, so that the pen pointmay be inser d therein in the usual manner. lVhen it is desired to remove the pen point, the sleeve 13 and spindle 12 are relatively rotated, so as to bring the slot letin reeister with therecess 16, as illustrated in i ire i, whereupon the shank of the pen' will ial'l through the slot Li. llherecess is of such shape-that it will prevent relative rotation of the pen point 15, and the spindle 1.2, during the rela tive rotation oil. the spindle 12 and sleeve 13. This arrangement also prevents the pen point from interfering with the relative rotation oi said sleeve and spindle, thereby insuring a smooth and uninterruptel move-- ment oft said parts. ll hen the recess 16 comes into register with the slot 14L, ample clearance provided for the shank of the pen, and the latter may he quickly removed from the pen holder, no matter how badly the pa ts may have become corroded by the ink. it will. be particularly noted that the shank of the pen point, interposed between the spindle 1: 3 and the sleeve 13, creates sufficient friction to prevent accidental rota-- tion of the sleeve upon the spindle, thereby insuring; that the pen will be retained in place while the pen holder is in use. The sleeve 13 is approximately of the same ereternal diameter as that of the body 10, so that there are no projecting parts lilrely to interfere with the normal. use of the pen holder.

Having thus explained the nature of the invention and described an operative manner of constructing; and using the same, although without attempting to set forth all oi? the forms in which it may l e made, or all of the forms Oil its use, what is claimed isr- 1. A pen holds" comprising a body por tion provided with a spindle at one end, rotatable sleeve ec;entrically mounted on said spindle and ham hp; :1 slot at one and exposing a port-ion ot the spindle, one means iiir preventing relative rotation oi? the spindle and a pen point during such relative r0- tation Oil the sleeve and spindle, as is. necessary to bring said slot into register with the shank of the pen point.

2. A pen holder comprising a body por: tion provided with a soini'lle at one end, and a rotatable sleeve ectentrically mounted on '1 indle and liavin r a slot at one end e posi A a. portion of: the spindle. said spindle having a lon itudinal recess to re ceive the shank oi: a pen point, whereby rela tive rotation of the spindle and the pen point is prevented during relative rotation of the sleeve and spindle, as said slot is brought into register with the said recess.

3. A pen holder comprising a body portion provided with a spindle at one end arranged eccentrieally with respect to the axis of the handle, a sleeve rotatably and eccentrically mounted on said spindle and havin a slot at one end exposing a portion of the spindle, and means for preventing relative rotation of the spindle and a pen point during relative rotation of the sleeve and spin dle, as said slot is brought into register with the shank of the pen point.

4:. A pen holder comprising a body portion provided with a spindle at one end arranged eecentrieally with respect to the axis 01" said body, and a sleeve rotatably and eecentrically mounted on said spindle and having a slot at one end exposing a portion of the spindle, the i e end of said spindle having a longitudinal recess to receive the shank of a pen point, whereby relative rotation of the spindle and .the pen point is pre vented during relative rotation of the sleeve and spindle, as said slot is brought into register with said recess.

In testimony .rhereoi have hereunto set my hand.
